摘要：
A new transient-state thermal model for power transformer for temperature prediction was constructed, based on the conventional thermal model. Two different intelligent learning methods, genetic algorithm (GA) and artificial neural network (ANN), were employed to construct thermal models from the on-site measurements. A comparison with experimental measurements showed that the transient-state model with recursion of the outputs, obtained using the GA learning, has a better performance than that of the conventional model.
